T0 at whom it may concern.-

Be it known that I, JOSEPH I-I. TEMPLIN, a citizen of the United Statesand a resident of Reading, in the county of Berks and State ofPennsylvania, have invented certain new and useful Improvements in aCombination of Dies for Use in a Machine for Making Barbed Strips, ofwhich the following is a specification. v

This invention is an improved contrivance of dies for producing twobarbed strips from one double blank strip by making two parallel linesof slits at intervals apart along the middle portion of a double blankstrip, so that the intervals of uncut web in one line are opposite themiddle of the slits of the otherline, which slits are in the mainstraight, but so diverge at two points toward the other line that theslits of the two lines meet thereat and cut apart and point the barbsand effect the separation of the two barb-strips. The barbs thus out arethen bent laterally to the strips for effecting the required projection,all in a simple and effective manner, as follows, referring to thedrawings, in which Figure 1 represents face views of the slitting andbending dies employed. Fig. 2 is a side elevation of the same with theblank strip between them; and Fig. 3 is a diagram of the blank strip,showing the action of the dies on it. Fig. 4 is aface view of amodifiedform of the slitting-dies. Fig. 5 is a diagram of the strip as cut bythe dies of Fig. 4.

With the following-described improved dies I take a plain fiat strip aas wide as two barb-strips to be made, besides the width of the barbs tobe produced on the strips, and make two lines of slits b c in it atintervals alongthe middle portion, with intervals of uncut webs clbetween the slits of each line, said lines of slits being apart fromeach other a distance equal to the width of the barbs e, and the slitsof each line being advanced relatively to the slits of the other line,so that the uncutwebs cl of each line are alternate with those of theother and midway along the slits thereof. Each slit, which is otherwisestraight, is divergent at two points f in the direction of the otherline of slits and to the extent of half the distance between them. Oneline of slits,

as l), is cut in advance of the other line by a pair of dies, as g 72,having corresponding d1- vcrgent portions f of the cutting-edges, andthe otherlinebysimilardies,asgh,which are located at the distance ofabout half the length of a feed movement of the strip apart along thefeedway, so that when the slits of the second line are made theirdivergent points match with one each of the similar points of two sli tsof the other line, and thus separate the barbs along the edge from thestrips, except where they remain connected by the uncut webs (Z andeffect thelateral ortransverse cutting by which the barbs are cut andpointed at the ends, and the separation of the barbed strips iscompleted, at the same time making center points that is, beveled alikeeach way. This leaves slight points j on the edges of the barb-strips7;, that may be trimmed off with suitable dies or not, as preferred.After being thus formed the barbs are bent laterally for the requiredprojection by suitable bending-dies Z m, of which it is preferred toemploy two pairs to bend the barbs alternately in opposite directions,and so that each pair bending two barbs at each operation the two willtogether bend the four which result from each operation of theslitting-dies simultaneously with the cutting of a like numbersuccessively.

These long dies, Figs. 1 and 2, are preferred for the greater amount ofwork they are capable of in a given time; but dies of a little less thanhalf the length of these may be used, as in Fig. 4, for the same methodof cutting the barbs, together with web-cutters p q, tobe used withthem, as, besides webs (1, they leave uncut webs cl, that have to besubsequently separated and with similar benders; but in this case thebenders will only operate with each alternate operation of the cutters,as only two barbs are cut at each operation. One pairof benders would besufficient, except that it is desired to bend the barbs alternately inopposite directions. In this arrangement the two pairs of theslitting-dies will be arranged the distance of one web cl apart. Theuncut webs cl between the slits are to be cut apart alternately in thedifferent lines of the slits.

The method is reserved for a separate application for a patent.

What I claim, and desire to secure by Letters Patent, is

1. The combination, of two pairs of shearing-dies, as g h and 9 7t,arranged to cut slits in two parallel right lines and atintervals ineach line, and each pair having a portion, as f, of the cutting-edgesdivergent toward the line of slits cut by the other pair, and being solocated one in advance of the other along the range of the blank stripto be cut that the slits of the two lines, elsewhere separating theedges of the barbs from the strips, but leaving them united for theirbase connection with the strips at the intervals of uncut webs betweenthe slits, meet at the divergent points, and the barbs are thereat cutapart and pointed and the barb-strips are partly or completely separatedfrom each other, substantially as described.

2. The combination of two pairs of shearing-dies, as g hand g h,arranged to out slits in two parallel right lines and at intervals ineach line, and each pair having two portions, as f, of the cutting-edgesdivergent toward the line of the slits cut by the other pair, and beingso located one in advance of the other along the range of the blankstrip to be cut that the slits of the two lines overlap, with the uncutwebs of one line midway along the slits of the other line, and that theslits of the two lines, elsewhere separating the edges of the barbs fromthe strips, but leaving them united for the base connections with thestrips at the intervals of uncut webs between the slits, meet at thedivergent points, and the barbs are thereat cut apart and pointed andthe barb-strips are completely separated from each other, substantiallyas described.

3. The combination of bending-dies, as Zm and Z m, adapted forbendingthe barbs laterally to the strip, with two pairs of shearingdies, as g hand g h, arranged to cut slits in two parallel right lines and atintervals in each line, and each pair having a portion, as

f, of the cutting-edges divergent toward the line of the slits cut bythe other pair, and being so located one in advance of the other alongthe range of the blank strip to be cut that the slits of the twolines,elsewhere separating the edges of the barbs from the strips, but leavingthem united for their base connection with the strips at the intervalsof uncut webs between the slits, meet at the divergent points, and thebarbs are thereat cut apart and pointed and the barb-strips arecompletely separated from each other, substantially as described.

, 4. The combination of web-cutters, as q r, with two pairs ofshearing-dies, as g 71, and g 7;, arranged to cut slits in two parallelright lines and at coincident intervals in each line, and each pairhaving a portion, as f, of the cutting-edges divergenttoward the line ofthe slits cut by the other pair, and being so located one in advance ofthe other along the range of the blank strip to be cut that the slits ofthe two lines, elsewhere separating the edges of the barbs from thestrips, but leaving them united for the base connection with the stripsat the intervals of uncut webs between the slits, meet at the divergentpoints, and the barbs are thereat cut apart and pointed and thebarb-strips nearly separated from each other, said web-cutters effectingthe complete separation by separating the uncut webs alternately in thedifferent lines of the slits, substantially as described.

5. The combination of bending-dies, as ml and m Z, adapted for bendingthe barbs laterally to the strip, and web-cutting dies, as q 0', adaptedfor separating uncut webs of metal left between the slits, with twopairs of shearing-dies, as g h and g h, arranged to cut slits in twoparallel right lines and at coincident intervals in each line, and eachpair havinga portion of the cutting-edges divergent toward the line ofthe slits cut by the other pair, and being so located one in advance ofthe other along the range of the blank strip to be cut that the slits ofthetwo lines, elsewhere separating the edges of the barbs from thestrips, but leaving them united for their base connection with thestrips at the intervals of uncut webs between the slits, meet at thedivergent points, and the barbs are thereat cut apart and pointed andthe barb-strips mainly separated from each other, said web-cutterseffecting the complete separation by separating the uncut websalternately in the different lines of slits, substantially as described.
